To determine the number of moles of helium in the balloon, we need to use the equation:
moles = mass / molar mass
Given:
Mass of helium = 0.30 g
Molar mass of helium = 4.0 g/mol
Substituting the given values into the equation:
moles = 0.30 g / 4.0 g/mol
Calculating the value:
moles = 0.075 mol
Therefore, the helium balloon contains 0.075 moles of helium.
